What does XKY Framing do?

XKY Framing (Yiwu Xinkuangyuan Machinery Co., Ltd.) designs and manufactures industrial framing machinery for picture frame, mirror, and cabinet door producers worldwide. Our product range includes fully automatic quad-corner underpinners (NN300), pneumatic and CNC underpinners (NN400–NN700), industrial stack cutting saws (NC500, NC600), dust-free miter saws (CT300), and pneumatic aluminium saws (CT400), plus a full range of V-nail fasteners.

Where is XKY Framing located?

XKY Framing is based at 77 Gexian Road, Yiwu City, Zhejiang Province, China — in the heart of the world's manufacturing hub. We supply framing machinery to customers globally.

What machines does XKY Framing manufacture?

XKY manufactures four main product categories: (1) Auto Underpinners — including the NN300 fully automatic quad-corner system (1,000+ frames/hour) and the NN400/NN500/NN600/NN700 pneumatic and CNC underpinners for joining 45° and 90° miter joints using V-nails. (2) Auto Cutting — including the NC600 industrial high-capacity stack saw and NC500 fully automatic stack cutting saw for double-miter cutting of MDF and wrapped profiles. (3) Frame Cutting — including the CT300 dust-free precision miter saw and CT400 pneumatic aluminium saw. (4) V-Nail Fasteners — compatible with all standard underpinner brands, available in soft, general-purpose, and hardwood grades from 7mm to 15mm.

How fast is the XKY NN300 automatic underpinner?

The XKY NN300 (SL-NN300) Fully Automatic Quad-Corner Underpinner joins all four corners of a frame simultaneously with a cycle time of 2–3 seconds, achieving over 1,000 joined frames per hour — up to 400% faster than manual operation. It is ideal for high-volume picture frame, mirror, and cabinet door production.

What is the difference between the NC500 and NC600 cutting saws?

The NC500 is a fully automatic stack cutting saw with a proprietary mold-based clamping system, best for complex or irregular moulding profiles up to 21.5" wide. The NC600 Industrial High-Capacity Stack Saw adds a 100mm (4") wide cutting range, anti-chip Three-Cut Mode, and zero-waste mirror-cut mode, boosting efficiency by 300–500% over manual saws. The NC600 is the flagship choice for large-scale laminated MDF and wrapped gesso frame factories.

Does XKY offer after-sales support and installation?

Yes. XKY provides a comprehensive service package: remote technical diagnostics via WhatsApp, WeChat, or Teams; full HD video tutorial libraries; on-site installation and operator training; a preventative maintenance program; 24-hour urgent support; and express spare parts dispatch (DHL/FedEx/UPS) from our Yiwu warehouse. Genuine spare parts are also available through xkyframing.com.

Are XKY V-nails compatible with other brands of underpinners?

XKY V-nail fasteners are made to the standard EN 10132 specification and are fully compatible with all major brand underpinners on the market. They are available in standard (0.30mm) and reinforced (0.38mm) thickness, in PS foam/plastic, general-purpose softwood, and hardwood grades, from 7mm to 15mm length.

The Press Head Rubber Band (压头橡皮筋) is a red polyurethane wedge-profile pad used in the pressing head assembly of framing machines. Its tapered 75x20x10mm body provides a controlled, graduated compression response that cushions the pressing head’s impact on the frame moulding during clamping.

Specification	Value
Length	75 mm
Width	20 mm
Thickness	10 mm
Profile	Tapered wedge
Material	Red Polyurethane

What is the profile shape of this rubber band?

It has a wedge (tapered) cross-section — 10mm thick at one end tapering to a thinner edge — allowing the pressing head to self-align against the moulding surface during the clamp stroke.

What material is used?

The pad is machined from red polyurethane, offering excellent compression strength, oil resistance, and surface hardness compared to natural rubber alternatives.

How many pads are typically used per pressing head?

Most pressing head assemblies use one or two pads depending on the machine design. Consult your machine's parts diagram for the correct quantity and orientation.

Press Head Rubber Band for Framing Machine – Polyurethane Wedge Compression Pad

The Press Head Rubber Band for Framing Machine is a precision-cut red polyurethane pad installed in the pressing head assembly of corner nailing and framing machines. Its wedge profile geometry is key to how the pressing head self-adjusts against varying moulding profiles, distributing clamping force evenly across the contact area.

Specifications

Length: 75mm. Width: 20mm. Thickness: 10mm (at thickest point). Profile: tapered wedge. Material: red polyurethane. The tapered geometry creates a self-aligning action as the pressing head descends.

Why Polyurethane?

Natural rubber pads in pressing heads harden and crack over time, especially in workshops where solvent-based stains or oils are used. The Press Head Rubber Band for Framing Machine uses polyurethane, which offers superior oil and chemical resistance alongside better long-term compression set resistance.

Installation

Remove the pressing head assembly. Remove the worn rubber pad from its seat. Clean the seat surface. Install the new pad in the correct orientation (thicker edge toward the high-load side as shown in your machine diagram). Reassemble and test clamp pressure.

Service Life

In high-volume production (500+ frames/day), replace pressing head rubber bands every 3-6 months. Lower-volume shops can typically extend service to 12 months between replacements.
